Fig. 4. — Illustration of fabrication processing steps of the retinal phantom (a) and schematic of the retinal phantom assembly for the eye model (b). (a) Fabrication processing: Step 1: The upper channel (Ch1) and the multilayered thin film are attached with oxygen plasma administered for a period of 1 min. Step2. The multilayered film (including the Ch1) and lower channel (Ch2) are punched to construct the inlet and outlet and to connect Ch1 and Ch2. Step 3: The multilayered film and Ch2 are attached with oxygen plasma administered for a period of 1 min. Step 4: The multilayered PDMS structure was cut to 30 mm and the ring pattern PDMS layer was attached on the structure. Step 5: Fluorinated ethylene propylene (FEP) tubes are connected in the inlet and outlet.
